I am using a ME program in German and I am trying to determine which tag in the PLC is activated by a latched button. However, upon reviewing the tag properties, I come across a tag that does not align with my PLC tags. I am curious to understand how this button corresponds to the PLC programming. Any insights on what the tag "#101.24" could represent?
Upon loading the display, it automatically verifies a parameter file and updates the #101 section with an actual tagname. This customization allows for the display to be used with various tags. To locate the parameter file linked to a Goto Display button, simply open the button's properties and check the specified name under 'Parameter file'. Next, navigate to the Explorer window, expand the 'Parameters' section, and open the corresponding file to locate the line containing #101=[something]. The value of [something] will indicate the specific tag you are searching for. This process ensures seamless integration of multiple tags within the display.
I have discovered that the "Parameter file" slot is currently empty, even after expanding the window. Does this imply that I am unable to proceed without obtaining the parameter file from the original equipment manufacturer (OEM)?
It seems likely that they are attempting to utilize faceplates following Siemens standards, possibly because the original machinery and programs were created on a Siemens platform. This indicates a strong connection to German engineering and technology in their operations.
I am curious if it is possible to retrieve the "Parameter file" directly from the panel. It seems that the HMI is reliant on this file to function properly. Can the parameter file be accessed through the panel interface?
Are there parameters listed on the left panel? I am trying to recall without access to ME or SE.
It sounds like you're looking at an address of a PLC bit. Generally, such references, "#101.24" for example, indicate a specific bit of a word in the PLC memory. It's addressed as the 24th bit in the 101st word. If it's a latched button, it might mean that this bit remains set (or true) until it's explicitly reset. As for why this tag doesn't align with your known tags, there could possibly be a discrepancy due to some programming steps you may have overlooked, or perhaps the system employed a separate or offset addressing scheme. Understanding the exact PLC model and auditing the entire program could help reveal more.
It sounds like you're dealing with a cross-referencing issue between your ME program and your PLC. The tag "#101.24" you're seeing suggests that, if you're employing a standard PLC data register format, the "101" represents the global data block and "24" is likely the byte within that block. That's standard IEC notation. Now, if the tag does not align with your PLC tags, it could well mean that the button in the ME program is linked to a different byte, perhaps one that's not currently being used in your PLC program. Without accessing your exact setup, it's difficult to make an accurate analysis, though. I would suggest doing a thorough check of your PLC program and how it maps to your ME interface, particularly focusing on that data block.

Answer: - Tag 101.24 in PLC programming could potentially represent a specific input or output point, a memory location, a variable, or a bit within a register. It is important to refer to the PLC program documentation or consult with the programmer to understand its exact significance.
Answer: - To troubleshoot a panel view tag discrepancy with PLC programming, you can start by verifying the tag properties in the panel view application and cross-referencing them with the PLC tags. Additionally, checking the logic in the PLC program that corresponds to the panel view tags can help identify any discrepancies or inconsistencies.
Answer: - To determine which tag in the PLC is activated by a latched button, you can analyze the logic in the PLC program that handles the button input. Look for any latching mechanisms or memory bits that store the button state. By tracing the logic associated with the button, you can identify the corresponding tag in the PLC programming.
Answer: - If you come across a tag in the panel view application that does not align with your PLC tags, you should investigate the tag properties in both systems to identify any discrepancies. It may be
